Social physique anxiety and physical activity behaviour of male and female exercisers

Despite females consistently reporting greater social physique anxiety (SPA), previous literature has yet to demonstrate whether SPA gender differences are linked to the way males and females perform physical activity. This study investigated an association between SPA and physical activity frequency, history of exercise, and physical activity intensity. Participants were represented by currently active users (N?=?33 males; N?=?31 females) of an on-campus university-run gym and completed a background physical activity questionnaire and the nine-item Social Physique Anxiety Scale. Participants also performed an exercise session at a self-selected level of exertion, with the intensity of each session measured via heart rate monitor. SPA was not associated with physical activity frequency, history of exercise (length of gym membership), or intensity for male and female exercisers. With respect to male participants, females reported higher SPA and a preference for performing higher intensity physical activity. Females and males also indicated a preference for performing aerobic and anaerobic physical activity respectively. Our findings suggest the experience of SPA does not deter body-conscious individuals from the performance of regular physical activity. Findings also suggest the discrepancy in male and female SPA is not linked to differences in the way physical activity is performed.     

The social experience of early childhood for children with learning disabilities: inclusion,competence and agency

This paper tells of the social experiences of three four‐year‐old children with learning disabilities as they negotiate their daily lives in their homes and early education settings in England. We apply a social model of childhood disability to the relatively unexplored territory of young children and use vignettes drawn from video observation to explore the interactive spaces contained in settings with different cultures of inclusion. Using a multimodal approach to the data we show the nuanced ways in which the children enact their agency. We explore the relationships between agency, culture and structure, and argue that children with learning disabilities are active in making meaning within social and relational networks to which they contribute differently depending on the barriers to doing and being that each network presents. Thus, the paper provides an original use of the notion of distributed competence.     

Pre-game perceived wellness highly associates with match running performances during an international field hockey tournament

This study examined the associations between pre-game wellness and changes in match running performance normalised to either (i) playing time, (ii) post-match RPE or (iii) both playing time and post-match RPE, over the course of a field hockey tournament. Twelve male hockey players were equipped with global positioning system (GPS) units while competing in an international tournament (six matches over 9 days). The following GPS-derived variables, total distance (TD), low-intensity activity (LIA; <15?km/h), high-intensity running (HIR; >15?km/h), high-intensity accelerations (HIACC; >2?m/s²) and decelerations (HIDEC; >?2?m/s²) were acquired and normalised to either (i) playing time, (ii) post-match RPE or (iii) both playing time and post-match RPE. Each morning, players completed ratings on a 0–10 scale for four variables: fatigue, muscle soreness, mood state and sleep quality, with cumulative scores determined as wellness. Associations between match performances and wellness were analysed using Pearson’s correlation coefficient. Combined time and RPE normalisation demonstrated the largest associations with Δwellness compared with time or RPE alone for most variables; TD (r?=??0.95; ?1.00 to ?0.82, p?=?.004), HIR (r?=??0.95; ?1.00 to ?0.83, p?=?.003), LIA (r?=??0.94; ?1.00 to ?0.81, p?=?.026), HIACC (r?=??0.87; ?1.00 to ?0.66, p?=?.004) and HIDEC (r?=??0.90; ?0.99 to ?0.74, p?=?.008). These findings support the use of wellness measures as a pre-match tool to assist with managing internal load over the course of a field hockey tournament.

Highlights

• Fixtures during international field hockey tournaments are typically congested and impose high physiological demands on an athlete. To minimise decrements in running performance over the course of a tournament, measures to identify players who have sustained high internal loads are logically warranted.

• The present study examined the association between changes in simple customised psychometric wellness measures, on changes in match running performance normalised to (i) playing time, (ii) post-match RPE and (iii) playing time and post-match RPE, over the course of a field hockey tournament.

• Changes in match running performance were better associated to changes in wellness (r = ?0.87 to ?0.95), when running performances were normalised to both time and RPE compared with time or RPE alone.

• The present findings support the use of wellness measures as a pre-match tool to assist with managing internal load over the course of a field hockey tournament. Improved associations between wellness scores and match running performances were evident, when running variables were normalised to both playing time and post-match RPE.

     

Enlightenment and measurement – a way to improve health among high school students

Abstract

This paper examines the effect of participating in a web-based health programme that promotes personal tracking of high school students’ own measurements of a number of health-related parameters. Danish cross-sectional survey data were used to examine the effects of the health programme on various health measures. Both quantile regression models and standard ordinary least squares (OLS) models were used to explore the correlations between the students’ participation in the health programme and their body mass index (BMI), body fat percentage, aerobic fitness, and well-being. Participation in the health programme increased BMI and aerobic fitness among students with a BMI or an aerobic fitness value ranging from the 25th percentile to the 75th percentile and reduced body fat percentage among students with the highest percentages of body fat. In addition, the health programme led to an increased feeling of wellbeing among students, especially those with high BMI levels and poor aerobic fitness. As the schools participated in the health programme on voluntary basis and at a financial cost to themselves, the positive effects of participation found can only be stated to be valid among students from committed schools.     

Changes in force production and stroke parameters of trained able-bodied and unilateral arm-amputee female swimmers during a 30 s tethered front-crawl swim

Abstract

This study examined changes in the propulsive force and stroke parameters of arm-amputee and able-bodied swimmers during tethered swimming. Eighteen well-trained female swimmers (nine unilateral arm amputees and nine able-bodied) were videotaped performing maximal-effort 30 s front-crawl swims, while attached to a load cell mounted on a pool wall. Tether force, stroke rate, stroke phase durations and inter-arm angle were quantified. The able-bodied group produced significantly higher mean and maximum tether forces than the amputee group. The mean of the intra-cyclic force peaks was very similar for both groups. Mean and maximum tether force had significant negative associations with 100 m swim time, for both groups. Both groups exhibited a similar fatigue index (relative decrease in tether force) during the test, but the amputees had a significantly greater stroke rate decline. A significant positive association between stroke rate decline and fatigue index was obtained for the able-bodied group only. Inter-arm angle and relative phase durations did not change significantly during the test for either group, except the recovery phase duration of the arm amputees, which decreased significantly. This study’s results can contribute to the development of a more evidence-based classification system for swimmers with a disability.
